PACKER DELIVER/IE8 FOR- FOLDING IVIACHINESL Application filed May 18,

My invention is directed to improvements in folding machines having two packer signature deliveries and particularly to manually operated means for independently changing the timing of the two sets of packer fingers with respect to their signature deliveries so that the signatures may be carried into their respective packers-with a minimum amount of disturbance, said manually operated timing means being operable whilethe machine is running.

A practical embodiment of my invention is represented in the accompanying drawings, in which- Fig; 1 represents the machine-in side elevation.

Fig. 2 represents the machine in longitudinal vertical section.

Fig. 3 represents a detail cross-section, on an enlarged scale, taken in the plane of the line III-III of'Fig. 1, looking in the direction of the arrows.

Fig. lrepresents a detail cross section, on an enlarged scale; taken inthe'plane of the line IV--IV of Fig. 1., looking in the direction of the arrows.

Fig. -representsa detail crosssection, on an: enlarged scale, taken in the plane of theline V V of Fig. 1, looking in the direction of the arrows.

The side framesof the machine are denoted by 1 and'2, inwhich side frames are mounted the upper and lower packer delivcries, comprising the usual troughs 3 and 4 and theirrespective sets of reciprocating packer fingers 5 and 6 uprising from their slides 7 andS.

Themeans for reciprocating the sets of packer fingers is constructed, arranged and operated as follows A driveshaft 9 is rotatably mounted in the side frames 1 and 2. Two wide faced spiral gear-s10 and 11 are mountedon and slidably interlocked with the drive shaft 9, which spiral gears mesh at all tlDICS' WIth their respective spiral gears 12 and 13, fast on the cam shaft 1 1, rotatably mounted in the side frames 1 and 2. Cams 15 and 16 are also fast on the cam shaft 14, which cams reciprocate'the upper and lower sets of packer fingers 5v and 6 througlrthe rock levers Hand 18, their-rack bars19 and 20, and the pinions-Ql and 22 which mesh with the racks 23 and 2-1 on the bars 19 and 1926. Serial no. 109,903.

and also with the racks 25 and 26 on the packer finger slides 7 and 8 respectively.

Manually operated means are employed for independently timing the packer fingers sothat the fingers will be caused to engage the signatures at the proper instant to permit the signatures to be forced into'their' respective packers with the minimum dis turbance, which means isherein showiras' being constructed, arranged andoperated as follows:

A screw shaft 27 is rotatably' mounted in the side frameQ for controlling thetiming of the upper set of packer fingers 5. This screw shaft 27 has a scre'w'-threaded-engagement with a yoke 28 slidably' mounted on a pin 29 projecting inwardly from the side frame 1 which yoke engagesthe hub of'tlie wide faced spiral gear 10, slidably interlocked with the drive shaft 9 on which it is mounted. This screw shaft'QT is provided with a suitable handle'30 located outside'of the side frame 2, in position for ready manipulation to rotate the screw shaft 27 in either direction for moving the spiral gear 10 laterally with respect to its in'term'e'shing' gear 12 on the cam shaft 14, to accurately time the upper set of packer fingers 5.

Another screw .shaft 31 is rotatably mounted in the side fra'me'fZ for controlling the timing of the lower set of packer fingers 6. Thisscrew shaft "31 has a screw-threaded engagement with a yoke 32, slidably mount edon a pin 33 projecting inwardly from the side frameQ, which yoke engages the hub of the wide faced spiral gear 11, slidably interlocked with the drive shaft 9 on which it is'mounted. This screw shaft 31 is providedwith a handle 34 located outside of the side frame 2 adj acentto the handle of the screw shaft 27 in position for ready manipulation'to rotatethe screw shaft 31 in either direction for moving the spiral gear 11 laterally with respect to its intermeshing gear 13 on the cam shaft 14, to accurately time the lower set of packer fingers6.

It is evident that various changes may be resorted to in the construction, form and ar-' rangem'ent ofthe several parts without departing from the spirit and scope of my invention; hence, I do not intend to be limited to the particular embodiment herein shown and described, but

hat I claim is 1. In a packer signature delivery, a plurality of sets of packer lingers, means for reciprocating them, and manually operated means for independently changing the timing of each set of packer fingers.

2. In a packer signature delivery, a plurality of sets of packer fingers, means for reciprocating them, and manually operated means for independently changing the timing of each set of packer fingers while the machine is running.

3. In a packer signature delivery, a plurality of .sets of packer fingers, means for reciprocating them including a drive shaft, a cam shaft and a pair of intermeshing spiral gears thereon for each set of packer fingers, and manually operated means for sliding a spiral gear of each pair along its shaft to independently change the timing of said sets of packer fingers.

4. In a packer signature delivery, a plurality of sets of packer fingers, means for reciprocating them including a drive shaft, a cam shaft and apair of intermeshing spiral gears thereon for each set of packer fingers, and manually operated means for sliding a spiral gear of each pair along its shaft to independently change the timing of said sets of packer fingers while the machine is running.

5.
